CARBURETER.

Specification of Letters Patent.. l Patgn-@d @hun 2y, 391@ appiicauoninea February 7, 191e. seriai no. $17,274.'

To all whom 'it may concern.'

Be it knownI thatI, FRANgois BAVEREY, citizen of the French Republic,residing at 36 Rue Pasteur, Oullins, Rhone, France, have invented newand useful Improvements in Carbureters for'l Explosion-Motors, of

which the following is a specification.

This inventionrelates to improvements in carbureters with concentricjets ofthe kind described in Patent No. 907953 of 29th December 1908.

vThe object of the invention is'to effect an energetic stirringv ofthegaseous mixture in the carbureting chamber in order 'to assure ahomogeneous mixture.

The annexed drawing illustra-tes the ap plication of the inventionv toaCarbureter comprising two concentric nozzles and shows the sameinvertical section.

The principal nozzle 1 fed by a constant level fuel containing reservoiris annular, and is provided centrally with a tube 3 open at both endsand communicating with the atmosphere at its lower part.. Thecompensator nozzle 2 fed by the compensator well 5, receiving its supplyfrom the well or reservoir 4,- isalso annular and concentric with thenozzle 1 and has its orifice at the same level as the oriiice ofnozzle 1. linmediately above these jets may be arranged a fixedhelicoidal baffle plate 6 surrounded by a tube 7. Air passes through thecentral tube 3 by which the gaseous mixture is stirred; this stirringcanbe further edected by a gyratory movement given to the mixture by ahelical member 6, the gaseous mixture formed by the spirit issuingf-romthe jets and by the central air. rThis initial mixing assists thehomogeneousness of the final explosive mixture formed in thecarburation` chamber 8 by means of the air flowing round the jets andentering through the ordinary inlet 9.

Instead of sucking air at atmospheric temperature-through the centraltube 3 the lair sucked in through said tube could be more or less heatedwhich would facilitate the vaporization of the fuel at the outlet of thenozzles and in the Carburation chamber. By suliciently heating the airthus sucked in heavy fuels such as petroleum, benzole or the like couldbe used.

What l claim as my invention and desire to secure by Letters Patent ofthe United `States is from said nozzles and said chamber.

2. in a carbureter for explosion motors the combination of an annularfuel nozzle, a second annular nozzle axially disposed Within said firstmentioned fuel nozzle, and having its orifice substantially in the samehorizontal plane as the orifice of said first mentioned nozzle, achamber Within said second nozzle adapted to supply air to the lorificesof said nozzles, and having its orifice in the same yhorizontal plane assaid orifices of said nozzles, a helicoidal baille plate, and a tubesurrounding said nozzles adapted to guide the fuel and air to saidbaffle plate.

3. In a carbureter for explosion motors, the combination of an annularfuel nozzle, aV second annular nozzle axially disposed within said firstmentioned fuel nozzle. a chamber within said second nozzle adapted tosupply air to the orifices of said nozzles, and means in the form of aninclosed balile plate for stirring and mixing together the fuel and airissuing from said nozzles and said chamber.' y

Ll. ln Va carbureter for explosion motors, the combination of an annularfuel nozzle, meansfor supplying air axially within said nozzle,` a tuberemovably secured to the nozzle and a helicoidal baffle plate inclosedby'tlietube and positioned-to divide said air axially and cause the sameto mix with the fuel fed by the nozzle.

5. in a carbureter, for explosion motors, the combination with anannular fuel nozzle. a tube axially thereof and open at both ends forsupplying air Within said nozzle, a tube secured to the nozzle at theupper end thereof and a baiiie plate suspended from above the nozzleaxially of the latter and in'closed by the tube to divide the air .callyplaced and spaced tubes providing a pair of annular nozzles havingindependent fuel supply channels and an inner tube of relatively largediameter through which air is drawn to commingle with the fuel issuingtherefrom, said inner tube being clearly open at both ends.

7. In a carbureter, the combination with a Carburation chamber having aninlet; of three spaced tubes arranged axially in said chamber andproviding a pair of continuously annular fuel nozzles, means forsupplying fuel through independent channels to said nozzles, the innertube having free communication with the atmosphere directly at its lowerend and means above the upper' ends of the tubes to stir and mix the airsupplied through the latter tube and the fuel from the nozzles, uponsuction being created in the' Carburation chamber prior to the mixing ofsaid air and fuel in the latter, to -assist Yin thev production'of ahomogeneous explosive mixture in said chamber'with the air enteringfrol'n, the inlet.

In Witness whereof I have signed this specification in the presence oftwo `Wit nesses. y
